Idiot, I wasn't even talking about iq. I was talking about the fact he was very 'asian' in overall temperament compared to his halfsibling raised in the same household and both the mother and I agreed it was genetics as I was raised the same way but genes can be strong. From every habit and ways that we know as we're asian so we know, got it? Just as an african doesn't become white overnight just because he moves to alaska. I don't have a formal study but I know what I've witnessed so if you lack that much common sense, it's your problem.
Your experience is still not science. In general you cannot take a single data point regarding the
behavior of a member of your family and either (a) assume its true globally for everyone or (b) assume that the temperament of
an individual speaks to the genetics of a race of a billion or more people.
Your anecdotal evidence is crap to start with. Anecdotal evidence isn't even enough to conclusively show that there is a difference amongst the races
at all, let alone to show the cause of that difference. At most, it shows that there are differences in the individuals you observed. The fact that you and your friends agreed that the differences you saw were caused by genetics is crap too, over and above the generalization you've made on the basis of your anecdotal observations.
If I may mirror your sentiment: if you lack an understanding of science such that you think your cited experience means anything, it's your problem.
And I would have to argue with you that genetics don't have something to do with iq, I think it does but nurturing does play a role in present and the potential you inherited. I agree with Iceaura's summation except for the diet aspect of african-americans, they like most americans enjoy a bounty of available food, sometimes much healthier than what whites eat. I would say other factors such as drug-infested and crime areas as well as cultural norms as well as genetics play a role in that aspect.
Did I say genetics have
nothing to do with IQ? No. What I said was that if one wants to assert that certain traits are genetic, one must be prepared to refute the alternate hypothesis that the traits in question are not genetic. Generally, that requires that you find
not only differences amongst the populations being studied, but that one must
control (statistically in this case, since experimental controls are likely infeasible) for other factors that influence that trait.
As an aside, you should know that the choices are not just "genetics" versus "nurture" in this case, as you seem to imply. There are
biological causes of temperament and other real differences between individuals that are not genetic. As such, while "nature v nurture" may be broad enough categories to capture difference, you can't assume that "nature," in this context, means "genetics."
Given how little you seem to understand about what "science" is, I'd be careful throwing around the word 'idiot" if I were you. The fact that you resorted to epithets at all bespeaks a certain lack of intellect. Couple that with your repeated indication that your barely analyzed anecdotal evidence conclusively demonstrates anything about the genetics of the children you observed and it becomes clear that your calling me an "idiot" is laughable.
